The Colorado Department of Regulatory Agencies Division of Insurance published a bulletin announcing the adoption of a new regulation, the amendment of two others, and the repeal of another. These changes will take effect on July 30, 2024.

Regulation 5-1-25 is newly adopted and requires insurers to notify policyholders of certain available coverages. Following the Marshall Fire that devastated the state in December 2021, HB23-1174 was passed which requires insurers to offer certain percentages of Extended Replacement Cost and Law and Ordinance coverage. Insurers are required to offer extended replacement coverage for an amount of at least 50% of the dwelling limit and offer law and ordinance coverage for an amount of at least 20% of the dwelling limit. Regulation 5-1-25 requires that insurers notify policyholders of those available coverages.

Regulation 4-2-11 is amended to create rate filing requirements for certain lines of insurance. Its purpose is to ensure health insurance rates are not excessive, inadequate, or unfairly discriminatory on limited benefit plans, excess/stop loss insurance, sickness and accident insurance, disability income, and other health benefit plans. It lays out which rates are considered "File and Use" and which are "Review and Approval".
